Functions
void	gis::split_gc (const Geometrycollection *gc, std::unique_ptr< Multipoint > *mpt, std::unique_ptr< Multilinestring > *mls, std::unique_ptr< Multipolygon > *mpy)
	Splits a geometrycollection into points, linestrings and polygons. More...
void	gis::gc_union (double semi_major, double semi_minor, std::unique_ptr< Multipoint > *mpt, std::unique_ptr< Multilinestring > *mls, std::unique_ptr< Multipolygon > *mpy)
	Cleans up overlapping geometries so that the geometrycollection is broken down into non-overlapping collections. More...
std::unique_ptr< gis::Geometrycollection >	gis::narrowest_multigeometry (std::unique_ptr< Geometrycollection > geometrycollection)
	Narrows down a geometrycollection to return a Multipoint, Multilinestring or a Multipolygon if the first level of the geometrycollection contains only points, linestrings or polygons. More...
